With a capacity of approximately 10 liters or 2.6 gallons, the tank is suitable for installations where connecting the heater to the vehicle’s primary fuel tank is impractical or undesirable.

The tank’s slim plastic construction measures approximately 16 × 16 × 3 inches, allowing it to be mounted in compatible vehicle, equipment, trailer and stationary-heater applications.

Part 221000202800 is also formatted as Eberspächer part number 22.1000.20.2800. It may be used with compatible Airtronic air heaters, Hydronic coolant heaters and other auxiliary heating systems requiring a separate fuel source.

A complete installation may also require the 130482 1.5 mm plastic fuel line, 36075300 3.5 mm fuel hose, 251888800102 fuel-line adapter, an application-appropriate fuel pickup, clamps and a heater-specific fuel-metering pump.

Always confirm the installation location, fuel type, mounting method and required connection components before ordering.
